The A-Frame was actually built to withstand much greater weight.... The Mirror Box/Cell/Mirror combined weight is around 800 pounds.

DOB自动系统

Now for the Rover, it will move itself....
The Rocker Box and Rover were built in parallel. I did not want to mar the Urethane coat trying to get a heavy steel structure built around it. The four steel sides bolt at their corners, with a scissor jack lift axle on one side and a trailer jack on the other for a three point drive system. The wheels are doubled to handle the weight of the entire lower scope and Rover. The trailer jack wheels are sprocketed to drive itself, I only need to steer.

In use.... I had First Light one night before a star party with some close friends. They said they would be real understanding if the scope was not done, but failure was not an option. I had First Light, got some much needed sleep, and picked up my friends at the airport. The scope is just awesome to use. Very smooth operation. Using the 8" touchscreen right at the eyepiece just adds another level to observing when you can access good photos for identifying objects. Since it's a touchscreen I interact with the laptop which is bolted to the lower portion of a truss pole which is shoulder high.

Awesome Night... Having the spring-loaded wheels on the ladder really helps. Little effort is needed to move the 70 pound ladder yet it settles to the ground when you step on it.

Additional fans for the 1.5" thick, 6"minor axis, secondary mirror. These will blow across the face of the glass to remove the boundary layer of heat.

The Mirror box received a new back cover to reflect the Sun's rays if I open the doors and it keeps the cold in.
